Indeed, car shoppers looking for a bargain can potentially find fleet gold at surplus auctions, where municipal, county, state, and federal agencies dispose of (usually) lightly used domestic cars and trucks. Knowing how those agencies use their vehicles can make or break the value of your find; buying an ex-Border Patrol Raptor in Texas may not be the best idea if you want a long-lived, trouble free truck.

That air presented the greatest obstacle to automotive speed and economy was understood intuitively, if not scientifically since the dawn of the automobile. Putting it into practice was quite another story. Engineers, racers and entrepreneurs were lured by the potential for the profound gains aerodynamics offered. The efforts to do so yielded some of the more remarkable cars ever made, even if they challenged the aesthetic assumptions of their times. We’ve finally arrived at the place where a highly aerodynamic car like the Prius is mainstream. But getting there was not without turbulence. (Read More…)
